Indirect proof discrete math
WebIn this general sense, proof by contradiction is also known as indirect proof, proof by assuming the opposite, [citation needed] and reductio ad impossibile. [1] A mathematical proof employing proof by contradiction usually proceeds as follows: The proposition to be proved is P. We assume P to be false, i.e., we assume ¬P.

WebIn mathematics, such proofs are very common place (indeed, we shall see two classic examples in the next section). However, as we discussed previously, some people take issue with the validity of such an approach since it invokes the law of the excluded middle. 1.

Web(5 points) In this question, you will give an indirect proof of the following theorem: Theorem 1. Let n be an integer. If n 2 + 2n − 4 is odd, then n − 2 is odd. (a) Write the contrapositive of the statement of Theorem 1. (b) Let m ∈ Z. Give the definition of what it means for m to be even. (c) Give an indirect proof of Theorem 1. IMPORTANT!

Since n is odd, n = 2k + 1 for some integer k. Then n2 = (2k + 1)2 = 4k2 + 4k + 1 = 2(2k2 + 2k) + 1. Now, let m = 2k2 + 2k. Then n2 = 2m + 1, so by definition n2 is even.
